An Irish nanny from Quincy was back in court Tuesday, as her attorney asked a judge to dismiss murder charges in the death of a 1-year-old Cambridge girl in January.

In Woburn Superior Court Tuesday, McCarthy’s attorney claimed that prosecutors presented “false and deceptive” information to a Middlesex County grand jury. A prosecutor said the presentation wasn’t misleading, and gave the panel a full picture of the girl’s injuries.

Judge S. Jane Haggerty didn’t immediately rule on the defense motion.

Aisling Brady McCarthy, 34, was charged with murder and assault and battery on a child on Jan 21, five days after Rehma Sabir died in Children’s Hospital.

McCarthy, who lived on Beale Street in Quincy, had been the family’s nanny in a Cambridge condo building. Police got a 911 call from the family’s residence on Jan. 14 – Rehma’s first birthday – that she was unconscious. Rehma had severe head injuries and was declared brain dead two days later.

McCarthy has been held on $500,000 cash bail since her arrest.

McCarthy has stayed out of sight in the arraignment dock at all her court appearances. Her history of legal troubles has come to light since her arrest.

She grew up in County Cavan and came to the Boston area on a tourist visa in 2002. Immigration authorities say she’s been her illegally since then. Since 2005 two restraining orders have been taken out against her. In 2007 she was charged with assaulting a female roommate, but the charge was later dismissed.

She married Irish native Don James McCarthy in Quincy in 2012.
